It is fitted for 3 kV DC and its key feature is the Russian traction equipment. In the next two years, this 160 km/h train will become the base platform for a whole line of domestic EMUs of the new generation, with the lengths possible between 4 and 12 cars, replacing the various versions of Lastochka based on the Siemens’s Desiro ML family.

The designation ES104 means: E - elektropoyezd (EMU), S - skorostnoy (rapid), 100 - it was agreed with RZD that the Lastochkas developed at UL will start with an inventory number of „100“, 4 - even digit standing for direct current. The new train with a power of 2,932 kW and a 2'2' + Bо'Bо' + 2'2'+ Bo'Bo' + 2'2' axle arrangement has an average acceleration of 0.7 m/s2 and can serve the platform heights of 200, 1100 and 1300 mm above rail top. The basic five-car Class ES104 unit provides for 416 seats (compared to 346 seats in the Class ES2G Standard unit), and a total capacity of 1,265 passengers. Entrance door width is 1,250 mm.
